The information is in the techniques.
If you know the techniques you need frames of references to understand.
interestingly enough, Saotome sensei said "aikido is principles, ideas, understand?" what can i say, his Japonglish is strange sometimes.
as far as frame of reference, it's drinking, partying, and general carousing and public disturbing after late night practice. as far as understanding aikido, still puzzle with why do we need to wear gi pant underneath hakama or wear anything at all? or why isn't there hot pink hakama with the lace trim, not that i would wear one, at least not in public, but why isn't there? why is there aiki ken but no aiki barbie? why aiki jo instead of aiki joe-bob or even billy-bob? and why can't we rap with O sensei doku?
